Abstract (en)
[origin: CA3000333A1] The invention relates to a device for producing a bone cement paste (54) from a monomer liquid (4) and a cement powder (5) as parent components of the bone cement paste (54) and for delivering the mixed bone cement paste (54), the device having a cartridge (1) having a cylindrical interior, wherein the interior of the cartridge (1) is closed on the front side except for a delivery opening for expelling the bone cement paste (54), wherein a delivery plunger (7), which is pushable in the direction of the delivery opening, is arranged in the interior of the cartridge (1) and wherein the cement powder (5) is arranged in the interior of the cartridge (1), between the delivery opening and the delivery plunger (7), wherein a closure means (9) is arranged on the front side, facing the delivery opening, of the delivery plunger (7), which closure means closes the delivery opening when the delivery plunger (7) is pressed against the front side of the interior of the cartridge (1), wherein the closure means (9) and/or an additional spacer blocks a further movement of the delivery plunger (7) in the direction of the front side of the cartridge (1) so that the delivery plunger (7) is spaced from the front side of the interior of the cartridge (1) at least in some areas and a dead volume remains in the interior of the cartridge (1) when the delivery plunger (7) is pressed against the front side of the interior of the cartridge (1). The invention also relates to a method for producing a bone cement paste (54) by means of such a device.
